In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2734-70-5, name is 2,6-Dimethoxyaniline belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 2734-70-5
To a solution of pentanenitrile (310 mg, 3.7 mmol) and 2-methoxy-6-methylaniline (518 mg, 3.40 mmol) in toluene (13 mL) at RT was added a solution of trimethylaluminum in toluene (1.7 mL, 3.4 mmol) at 0° C. The reaction mixture was heated at 110° C. for 1 h. The cooled reaction mixture was quenched with saturated solution of Rochelle’s salt (5 mL) and stirred at RT for 30 min. The reaction mixture was extracted with EtOAc (3×20 mL). The combined organic layer was washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography eluting with 20-100percent EtOAc/hexanes with 0.5percent Et3N to give Compound 1a (450 mg, 56percent) as a brown oil. LCMS (Method D) retention time=0.65 min, m/z=237.1 (M+H). 1H NMR (500 MHz, chloroform-d) delta 6.88 (t, J=8.4 Hz, 1H), 6.51 (d, J=8.3 Hz, 2H), 4.68-3.89 (m, 2H), 3.71 (s, 6H), 2.33 (br. s., 2H), 1.84-1.52 (m, 2H), 1.49-1.24 (m, 2H), 0.89 (br. s., 3H).
The synthetic route of 2734-70-5 has been constantly updated, and we look forward to future research findings.
